From a8ec4437cd52b2258c77d6b4195c927139c4ced5 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Wed, 27 Apr 2016 11:04:53 +0100 Subject: [PATCH] migration: remove use of qemu_bufopen from vmstate tests Some of the test-vmstate.c test cases use a temporary file while others use a memory buffer. To facilitate the future removal of the qemu_bufopen() function, convert all the tests to use a temporary file. Reviewed-by: Dr. David Alan Gilbert Signed-off-by: Daniel P.
